A man is fighting for his life after being knifed in north-west London.
Police and paramedics were scrambled to Eton Grove, Queensbury, to reports of a stabbing at about 6.30pm on Wednesday.
The victim, aged in his 20s, was rushed to hospital, where he remained in a critical condition.
No arrests have been made, Scotland Yard said.
A Section 60 order, which allows officers to stop and search anyone, is in place until midnight covering the areas of Queensbury - both Brent and Harrow - and Kenton.
The Brent borough branch of the Met Police tweeted earlier: “A section 60 is in place until midnight tonight covering the wards of Queensbury (both Brent and Harrow) and Kenton following a stabbing in Eton Grove.
It added: “Man in his 20s en route to hospital in a critical condition. No arrests.”
